Management Research On Payment And Changing Of Design-building Contract For Some Large-scale Cross-sea Traffic Infrastructure Project

With the maturing management of the design-and-build contract format in China, it is a matter of interest for the contractors as well as a topic of discussion and study for the project owner, to fully exploit the advantages of the design-and-build contract format through establishing a more reasonable, efficient, rigorous, and normative management model of measurement, payment and construction change control for large-scale cross-sea infrastructure projects. This paper investigates the management models for measurement, payment and construction change control of a certain mega project in China and proposes, through analysis of the management practice of this specific project, the systems, models and methods of measurement, payment and construction change control more suitable to big cross-sea transportation infrastructure projects in China.This paper firstly explores how the system of measurement, payment and construction change control was designed to suit the characteristics of the study project. It then goes on to discuss how the models of measurement, payment and construction change control were chosen, and how the expected effects were realized; management results are also examined and summarized through analysis of actual cases. The final part of the paper sums up the study and presents future research prospects, with the intention to provide references and possible research directions on the measurement, payment and construction change control for management staff and researchers of similar projects that adopt the design-and-build contract format.
